It’s true, I too have succumbed to the HTML5 craze and decided to create an HTML5 game for a competition organized by Google - Mám Padla. So please, the +1 button will help me :)
The game is called Dog Pee and your task is to out-pee your opponents. You injure them with your pee, they injure you with theirs. The clock is ticking. The game currently has 10 levels. I drew the graphics by hand, my fingers are still stained with the black ink. You can find a small making-of in the gallery :)
